thermo-pi-core v0.0.1

Thermo-Pi-Core

This is a small set of core libraries used by various thermo-pi modules. Add this to your thermo-pi project using

npm install --save thermo-pi-core

Prerequsites

• To use the w1-therm-manager the w1-gpio and w1_therm modules need to be enabled.

  • See the guide at REUK.co.uk for further instructions.

• To use the dht-manager the pigpiod daemon must be running.

  • Download and compile the binary from DHTXXD
  • See the guide at rototron for further instructions.

Libraries

w1-therm-manager

• properties - Defines the properties for w1-therm

• getSensors() - Returns a list of detected sensors.

• read(sensor) - Returns the temperature data for the defined sensor in degrees centigrade.
  sensor - A single sensor that will be read.

• Properties
  location - The path to the DS18B20 one-wire sensors.
  prefix - The sensor constant prefix.

dht-manager

• properties - Defines the properties for dht

• read(pin) - Reads temperature and relative humidity data from the defined pin. pin - The GPIO pin to read.

• Properties
  binary - The path to the dhtxxd or compatible binary.

  • A ${PIN} parameter will be used to define the GPIO pin to read.
  • Output is status:int temp:float(C) humidity:float(%)

  • Status is 0 - Ok 1 - Crc 2 - Bad data 3 - Timeout

    pins - The GPIO pins where a DHT sensor is connected (optional, csv)
